Upon reaching level 80, he may approach you in one of the major cities, telling you, "The time has come." You can then ask him what he means by this, or if you exited the conversation when he tried to talk to you, you will be able to ask him what he was saying before. Both options will lead to the same response with him saying, "I have done all that can be done. There is nothing left. No quests to be undertaken. No villains to be slain. No challenges to face. Except for you. You are my last challenge. Only you can send me to Sovngarde with honor. Make your preparations. When you are ready, come find me at my last vigil."

When at his last vigil, he will not acknowledge your motive for coming to see him, and will only respond with generic comments until you attack or provoke him. After doing so, he will fight back, occasionally using taunts such as "Show me you are the hero they say you are!", "I am the Ebony Warrior!", and "Kill me already!" Other combat dialogue includes: "That's the spirit!" and "Hit me harder!", which he may say when you attack him. Upon dying, he will say: "At last. Sovngarde..."

While he can be harmed by falling damage, you must damage him after he lands but before he begins the animation for standing back up for the damage to take effect. Otherwise, he can survive any fall and will actually be restored to full health after he gets back on his feet.[verification needed — see talk page]

He is one of the tallest NPCs in the game.

He is the only non-Nord, non-Elder NPC capable of using dragon shouts.

Despite being a Redguard, the Ebony Warrior will say "At last, Sovngarde..." upon being killed.

He has a unique perk with an ID of DLC2EbonyWarriorPickPocketMod. This perk reduces your chance to successfully pickpocket him by 110%. You can still pickpocket all his equipment with a sufficiently high skill along with Fortify Pickpocket effects.

He is one of the Named NPC's specifically immune to Paralyzing effects from equipment and poisons.

Ranged attacks that should strike his head will instead pass through him with no effect, due to his hitbox not covering his body above the shoulders.

Even if you manage to pickpocket all of his equipment off him on your first meeting, he will spawn at the Last Vigil with a full set of his armor, but no weapons. This may also happen in the city if you save, reload, and turn him hostile. ?
